SIDE BEARING FOR RAILWAY CARS.

Application filed June 8, 1925. Serial No. 35,820.

This invention relates to new and useful improvements in side bearing for railway cars and the like and the object of the invention is to provide a robust bearing of the class stated which will be easily erected and eflicient in service.

Another object is to provide a forged bearing of the class stated which will be economically manufactured and easily assembled.

In my invention the main body of the bearing is made in two parts both parts being punched or blanked out from a single strip of material. Depressions or indents are formed in both parts by means of a press before the parts are assembled. The two parts are held together by any suitable means to form a rectangular box open at the top and bottom. The depressions are adapted to receive the extended centres of a supporting roller and are so formed that they will allow a certain amount of free horizon tal movement to the roller when the bearing is in its assembled condition. The roller is mounted on a one piece filler which fits snugly between the sides of the box and is held in position by means of the rivets or bolts attaching the parts of the box together.

Lugs are formed integral with the bearing for attaching the device to the underside of a railway car.

In the drawings z- Figure 1 is a plan view of a strip of metal showing the method used in forming the main body of the bearing.

Figure 2 is a plan view of my improved side bearing in its assembled condition.

Figure 3 is a sectional end elevation of the bearing taken on the line 33 Figure 2. Figure 4 is a sectional side elevation of the bearing taken on the line 4- 1 Figure 2.

Referring more particularly to the drawings, 11 designates a strip of material from which the main body of the bearing is to be manufactured. The main body of the bearing is made in two parts or sections 12 and 13 cut from the strip 11. To simplify the description I will describe the method of the bearing from the strip until it is in its assembled condition ready to receive the roller and filler hereinafter described. The parts 12 and 13 are first blanked out to the exact size and shape to complete the main body of the hearing as shown in full lines 14: and 15.

The blanked out portions are then subjected to a drop forging operation to form} a T shaped indent or depression 16 in each. of the blanks midway between their ends. In the third operation holes 17 are formed in close proximity to each end of the blanks and drainage slots 18 may also be formed in the same operation. In the fourth opera tion the ends 19 and 20 of the blanks are bent upwardly at right angles to the main body of said blanks and are bent in such a manner that the ends 19 will fit snugly between the ends 20 and. the corresponding holes 17 and drainage slots 18 will coincide with one another. In the fifth operation the lugs 21 are bent outwardly from the main body of the blank to form an attaching means and through which holes 22 may be formed for the attaching bolts or rivets which pass through the underside of the railway car (not shown) to which the bearing may be attached. In the last operation the parts are fitted together and the rivets 32 and 33 placed through the holes 17 to hold the parts together, so that they form a rectangular box open at the top 23 and bottom 24 with the vertical portion of the shaped depression allowing free access for the insertion of the ends or projections 25 of the rollers 26. The roller is then placed in position and a one piece filler 27 is then inserted in the bottom, recesses 28 being formed therein to allow the filler to clear the rivet heads 29. The rivet heads also engage with the lowermost ends of the recesses to hold the filler in its assembled position. The innermost heads 30 of the rivets 33 may be countersunk to allow the roller to move from end to end of the hearing.

In the drawing a three lunged bearing is shown but this may be modified to suit the requirements of the railroad for which the bearings are being manufactured. Othermodifications may be made in the construction of the bearing without departing from the spirit of the invention. The ends 19 are preferably made as shown that is fitting. closely into the corners 31 of the bearing to prevent distortion of same while in use. All corners may be rounded olf to prevent accidents which may occur in handling the bearing during assembly of same.

It will be seen from the foregoing that a side bearing made in the manner disclosed may be economically manufactured both as regards time and material as this device may be manufactured from roll steel plates a much stronger and more homogeneous andreliable material than that used in bearings which are made of cast material.

In the drawing I have shown a cast tiller but a rolled steel filler may be used. In use it has been found that the ends being formed of a double layer of metal stand up better to the strain and shocks which occur in bear ings of this class when compared with the usual type of hearings in use at the present time. The T-sha'ped depression allows easy insertion of the roller and the filler is held in position by the attaching means for the 1 arts of the box.

Having thus described my invention. what I claim is V r 1. In a side bearing for railway cars and the like two main body portions ada'pted to [it one withinthe other to form a rectangular box open at thetop and bottom and having double ends secured togetheig said body portion being formed with T shaped depressions located mid-way between the ends of the box and extending upwardly from the bottom thereof lugs extending outwardly from the bottom of the box to form an attaching means for the bearing, a roller having extended ends adapted to fit into the T- shaped depressions and a one piece tiller fitting snugly within the box and having re cesses formed in its ends to engage with the securing means for the body portions to hold the filler in position.

2. As a new article of manufacture, a boxing for side bearings of the character described, comprising two sheet metal blanks formed with right angularly extending end portions and assembled in box formation with the end portions of one blank disposed in lapping engagement with the responding portions of the other blank and secured thereto to form the ends of a. box, the sides of which are formed by the opposing main body portions of th bl111kS,'tll main. body portion of each blank being formed with a depression shaped to provide a track for the conventional bearing roller.- In witness whereof, I have hereunto set my hand.
